That has already been a thing that has existed.

I once successfully quit smoking by buying a pack of cigarettes made with tobacco that had been cleansed of its nicotine. I bought them one evening on the way home from work.

That first night was rough because nicotine withdraw be like that. The second day was still not great, but it was easier. By the third day, I'd had enough. On about the fourth day, I threw the rest away because they were just tiresome.

They were lousy. They tasted terrible compared to my usual brand. And smoking them did nothing to quench my addiction-driven craving for nicotine -- the reward for my brain and my body simply wasn't being delivered.

And it worked.

My theory for the method of operation goes something like this:

My brain was used to pushing the button and receiving candy, and it needed that candy (or at least it thought that it did).

But this was disruptive of that: The button was still there and I could push it freely. But no matter how many times I pushed it, no candy was received. This went on just long enough that I no longer felt compelled to need candy (because nicotine addiction had enough time to fade out).
